Thread Pitch: 1/2x28 (AR-15 standard) Caliber: 5.56 NATO / .223 Rem Kit Includes: A2 compensator + crush washer Model/SKU: 55DA535 UPC: 815835018263 Platform: AR-15 / M4 (1/2x28 threaded barrels) Why choose the CMMG A2 Compensator Kit? Proven A2 geometry The familiar birdcage porting helps tame muzzle rise and reduce visible signature compared to a bare muzzle—without the blast and concussion of aggressive brakes. Turn-key installation Comes with a crush washer so you can time the ports correctly in minutes—no extra parts hunting. Duty-ready durability CMMG machines the compensator for dependable thread engagement and long service life, then applies a hardwearing finish for corrosion resistance in rain, sweat, and range grime. Non-directional look with top timing Standard A2 orientation vents gas optimally when timed with the included washer; the closed bottom also helps minimize dust signature when shooting prone. Budget-friendly performance Light, compact, and effective—an easy upgrade over a thread protector and a trusted option for general-purpose AR carbines. Ideal use cases General-purpose carbines: Balanced control and low concussion for classes, range days, and training. Home & ranch rifles: Reliable, low-maintenance muzzle device that won’t punish shooters or bystanders with excessive blast. Build refresh or OEM replacement: Keep your rifle compliant with common configurations and accessories. Field & patrol style setups: Classic A2 profile mates cleanly with most A2 front sight bases and standard handguards. What’s in the box CMMG A2 Compensator (1/2x28, 5.56) Crush Washer (for timing/alignment) Installation (quick guide) Unload & clear the firearm. Remove existing muzzle device and any old washer/shims. Slide on the crush washer (beveled side toward the muzzle device). Thread the compensator on by hand until snug. Time the device so the closed ports are at the 6 o’clock and the open slots at 12 o’clock. Tighten 1/4 turn at a time until timed—do not over-torque. Function-check and verify clearance with your rail/handguard before live fire. For suppressor use or specialty setups, follow the suppressor manufacturer’s mounting guidance and do not use a crush washer unless specified.

Frequently asked questions Q: Will this reduce recoil like a dedicated brake? A: The A2 offers moderate muzzle rise control and some flash reduction. For maximum recoil reduction, a multi-port brake works better—at the cost of extra blast. Q: Do I need shims? A: The kit includes a crush washer, which is typically all you need. Shims are optional if you prefer finer timing adjustments. Q: Can I pin/weld this to reach 16"? A: The A2 is often used for P/W builds, but verify length and local compliance. Many builders choose extended devices specifically designed for pin/weld. Q: Is it compatible with suppressors? A: This is a standard A2 compensator, not a suppressor mount. If you plan to run a can, choose a suppressor-compatible muzzle device per the can manufacturer. Best practices & tips Use proper tools: An armorer’s wrench and a reaction rod or upper receiver vise block protect your receiver. Recheck torque/timing after first range session; heat cycles can settle the washer slightly. Avoid threadlocker unless manufacturer specifies; heat can break down many compounds. Keep ports clean: A quick brush removes carbon that can accumulate in the slots.
